 OUTLINE OF THE ESTIMATION OF GPS-ORBITS AND EARTH ROTATION PARAMETERS
 AT THE ESOC PROCESSING CENTRE FOR IGS

 J.M.Dow, J.Feltens, T.J.Martin-Mur, C.Garcia-Martinez

 Description of analysis for period 1993 Nov 21 - Nov 27
                                                        (week 0724)
 1. SOFTWARE USED:   GPSOBS/BAHN-Version 5

 2. MODELS USED AND PARAMETERS ESTIMATED/FIXED:

  For a description of models and parameters used ==> see IGS - Mail  51
  For updates of the models and parameters used   ==> see IGS - Mail 114 and
                                                      see IGS - Rep. 224,277

 3. REMARKS: With the beginning of week 0724 we have included SV-34/PRN04
             into our routine IGS-processing and we have added the two sites
             RCM5 (Richmond) and KOSG (Kootwijk).
             The orbit accuracy of SV-09/PRN13 is again of reduced quality,
             since it has only been tracked in parts of its orbit. The track-
             ing data is only about 50% of the data obtained for the other
             satellites.

 4. GROUND STATIONS: Boucher and Altamimi, IGS workshop Berne 24-27 March'93
                     IGS/IERS station coordinates in the ITRF91 at 1992.6
